AVRounding

public typealias AVRounding = CFFmpeg.AVRounding

  • Round toward zero.

    Declaration

    Swift

    public static let zero: AVRounding
  • inf

    Round away from zero.

    Declaration

    Swift

    public static let inf: AVRounding

  • Round toward -infinity.

    Declaration

    Swift

    public static let down: AVRounding
  • up

    Round toward +infinity.

    Declaration

    Swift

    public static let up: AVRounding

  • Round to nearest and halfway cases away from zero.

    Declaration

    Swift

    public static let nearInf: AVRounding

  • Flag telling rescaling functions to pass INT64_MIN/MAX through unchanged, avoiding special cases for #AV_NOPTS_VALUE.

    Unlike other values of the enumeration AVRounding, this value is a bitmask that must be used in conjunction with another value of the enumeration through a bitwise OR, in order to set behavior for normal cases.

    av_rescale_rnd(3, 1, 2, AV_ROUND_UP | AV_ROUND_PASS_MINMAX);
// Rescaling 3:
//     Calculating 3 * 1 / 2
//     3 / 2 is rounded up to 2
//     => 2

av_rescale_rnd(AV_NOPTS_VALUE, 1, 2, AV_ROUND_UP | AV_ROUND_PASS_MINMAX);
// Rescaling AV_NOPTS_VALUE:
//     AV_NOPTS_VALUE == INT64_MIN
//     AV_NOPTS_VALUE is passed through
//     => AV_NOPTS_VALUE
